Next with interpreter operation.
Fig. 2 shows the sequential chart of the operation of being carried out by UE shown in Figure 1 21 that is used for location registers.To explain the location registers operation of carrying out by UE 21 with reference to figure 2.
When UE 21 opening power or when detecting the change of its position, make position register request.
If UE 21 is in IP network 5, UE 21 knows that according to the information by AP 3 notices it is arranged in IP network 5, thereby, when UE 21 inserts call control servers 1, use telephone number at IP network 5 as caller number (step S1).
If correctly authenticated UE 21, subscriber database 4 registration location information (step S3).Then, subscriber database 4 transmits the subscriber information (step S4) of the UE that has made position register request to call control server 1.
It has received the subscriber information (step S5) that is transmitted to call control server 1 to subscriber database 4 responses.When the transmission response that receives from the subscriber information of call control server 1, subscriber database 4 is finished (step S6) to call controller 1 notice location registers.Then, call control server 1 is finished (step S7) to UE 21 notice location registers.
On the other hand, if UE 21 in mobile communications network 15, UE 21 inserts mobile switch systems 11 (step S11) via the base station in the mobile communications network 15 13 and base station control device 12.Because UE 21 knows that according to the information by base station 13 notices it is arranged in mobile communications network 15, UE 21 uses telephone number at mobile communications network 15 as caller number.
When mobile telephone exchange network 11 detects subscriber information by the subscriber database in the IP network 54 management UE 21, at first make position register request (step S12) to HLR 14.If it is effective terminals in the mobile communications network 15 that HLR14 identifies UE 21, and has correctly authenticated described terminal, the position (step S13) of HLR 14 registration UE 21.HLR 14 registration location information, and finish (step S14) to terminal authentication and the location registers of mobile switch system 11 notice UE 21.
Can based on such as will transmit from UE 21, be included in the subscriber ID the position register request or the information of Termination ID, carry out and be used for mobile switch system 11 and detect method by the subscriber information of the subscriber database 4 management UE 21 of IP network 5.Mobile switch system 11 is based on the information of subscriber ID or Termination ID, judge UE 21 whether not still mobile communications network 15 and also be accessing terminal of IP network 5.If it is effective terminals that mobile switch system 11 detects UE 21, whether the subscriber information of judging UE 21 is by 4 management of the subscriber database in the IP network 5.Note, if UE 21 is defined as being connected to the terminal of IP network 5, the location registers operation become with traditional mobile communications network in identical, that is, only in HLR 14, carry out terminal authentication and the location registers of UE 21.
The flow chart of the control operation that Fig. 3 shows when UE 21 is in mobile communications network 15, carried out by the mobile switch system among Fig. 2.
When 21 executing location of the UE in the mobile communications network 15 registration request (step S21), mobile switch system 11 judges it is the subscriber information (step S22) of management UE 21 in IP network 5 or in mobile communications network 15.When mobile switch system 11 detected the subscriber information of management UE 21 in mobile communications network 15, mobile switch system 11 is to HLR 14 transmission locations registration request, and was the same with common mobile phone, will be by HLR 14 executing location registration (step S22: not).Then, mobile switch system 11 is from the subscriber information of HLR 14 acquisition UE 21, and completing place registration process (step S26).
On the other hand, when mobile switch system 11 detected the subscriber information of management UE 21 in IP network 5, mobile switch system 11 request HLR 14 carried out the authentication (step S23) of the UE 21 in the mobile communications network 15.If correctly authenticated UE 21, the subscriber database 4 in the mobile switch system 11 request IP network 5 comes executing location registration (step S24) by transmission location registration request.Then, mobile switch system 11 is from the subscriber data of subscriber database 4 reception UE 21, and completing place registration process (step S25).
As mentioned above, the positional information that UE 21 is occurred registers in the subscriber database 4 in the IP network 5 by the position register request of being carried out by UE 21.Equally, as mentioned above, if UE 21 is in mobile communications network 15, the identifying information of the mobile switch system 11 that can only the executing location registration be asked is registered as the positional information in the subscriber database 4, is used for indicating UE 21 whether to be in mobile communications network 15.
Next, will be explained in the calling attended operation of the UE 21 that carries out in IP network 5 and the mobile communications network 15 each.
At first, will explain that the exhalation from UE 21 connects.
Fig. 4 shows the sequential chart of the operation that being used to breathes out connects when UE telephone calling shown in Figure 1.
When UE 21 was in IP network 5, UE 21 used telephone number at IP network 5 as the request of caller number call transmission.Pass through AP 3 receipt of call requests (step S31) by call control server 1.Call control server 1 identification is included in the connection destination telephone number in the call request, and definite call request is the exhalation connection at PSTN 31.Call control server 1 sends call request signal (step S32) to PSTN 31.
Note, at UE 21 with connect in the communication between the destination, carry out relaying, and be converted to and have the media signal that needs form with PSTN 31 signal posts, and transmit by 2 pairs of IP groupings of media gateway from the UE21 transmission.On the contrary, will in media gateway 2, convert IP grouping and be transferred to UE 21 from the signal of PSTN 31 to.
With the operation of explaining from the exhalation connection of the UE in the mobile communications network 15 21.
UE 21 uses telephone number at mobile communications network 15 as the request of caller number call transmission, and by mobile switch system 11 by base station 13 and base station control device 12 receipt of call requests (step S33) in mobile communications network 15 inside.
When mobile switch system 11 goes out the subscriber information of management UE 21 in IP network by being included in information Recognition in the call request, the call control server 1 call transmission request step (step S34) of mobile switch system 11 in IP network 5.
Call control server 1 identification is included in the connection destination telephone number from the call request of mobile switch system 11 transmission, and determines that described call request is the exhalation connection at PSTN 31.Call control server 1 sends call request signal (step S35) to PSTN 31.
Fig. 5 shows when the UE telephone calling in mobile communications network, the flow chart of the control operation of being carried out by the mobile switch system among Fig. 4.
When 21 telephone calling of the UE in mobile communication system network 15 (step S41), receive the call request that is used to call out by mobile switch system 11.Mobile switch system 11 judges that by the information that use is included in the call request subscriber information of UE 21 is to manage (step S42) in IP network 5 or in mobile communications network 15.If mobile switch system 11 is identified in the subscriber information (step S42: deny) of management UE 21 in the mobile communications network 15, and is the same with common mobile phone, carry out call treatment (step S44) at this calling.If mobile switch system 11 is identified in the subscriber information (step S42: be) of management UE 21 in the IP network 5, the call control server 1 call transmission request (step S43) of mobile switch system 11 in IP network 5.
Will be explained in the operation of the call control server 1 when making a call by the UE in the mobile communications network 15 21.
Fig. 6 shows when the UE telephone calling in mobile communications network, the flow chart of the control operation of being carried out by the call control server among Fig. 4.
As the UE in the mobile communications network 15 21 during telephone calling, step S43 (same, step S34 among Fig. 4) the call control server 1 call transmission request to IP network in of mobile switch system 11 in Fig. 5.Call control server 1 in the IP network 5 receives from the call request (the step S51 Fig. 6) of mobile switch system 11 transmission.
When call control server 1 received call request from mobile switch system 11, call control server 1 was included in the connection destination (step S52) that the information Recognition in the call request is called out by use.When the connection destination that call control server 1 identifies calling was terminal in the IP network 5, described terminal was (the step S52: be) that is controlled by call control server 1, and the ordinary call termination that call control server 1 is carried out in the IP network 5 is handled.On the other hand, when the connection destination that call control server 1 identifies calling is not IP network 5 but terminal among the PSTN 31 (step S52: not), call control server 1 to PSTN 31 call transmission requests as the calling (step S54) that has transmitted.
Note, carry out relaying by the communication between 2 couples of UE 21 of media gateway and the connection destination.
To explain that termination is addressed to the operation of the incoming call of UE.
Fig. 7 shows the sequential chart to the operation of the incoming call connection of UE shown in Figure 1.
At first, the incoming call request (step S61) that receives from PSTN 31 by call control server 1.Where the call control server 1 that has received the incoming call request appears at (step S62) to subscriber database 4 inquiries as the UE 21 on call intent ground.
Explain as the reference position log-on operation, comprise the subscriber information of the positional information of UE 21 by subscriber database 4 management.Therefore, call control server 1 is notified positional information according to the positional information of its management to call control server 1 to the subscriber database 4 that it has inquired about the positional information of UE 21.
If UE 21 is in IP network 5, subscriber database 4 returns in subscriber database 4 positional information (step S63) of the UE 21 in the IP network 5 of registration to call control server 1.The call control server 1 of positional information that has received UE 21 is carried out at the incoming call termination of UE 21 and is handled (step S64) via the AP 3 that links to each other with IP network 5.
On the other hand, if UE 21 appears in the mobile communications network 15, the identifying information of the mobile switch system 11 of subscriber database 4 by detecting the positional information be registered as UE 21 in subscriber database 4 identifies UE 21 in mobile communications network 15.Then, subscriber database 4 sends inquiry to mobile switch system 11, is used for asking the positional information (step S65) at the UE 21 of mobile communications network 15 management.Respond described inquiry, mobile switch system 11 is returned the positional information (step S66) of the UE 21 of management in mobile communications network 15 to subscriber database 4.Then, subscriber database 4 returns from the positional information (step S67) of the UE 21 of mobile switch system 11 receptions to call control server 1.Therefore, call control server 1 has been known the mobile switch system 11 of control UE 21, transmits incoming call request (step S68) to mobile switch system 11 then.The mobile switch system 11 that has received the incoming call request from call control server 1 is carried out at the incoming call termination of UE 21 and is handled (step S69) via base station control device the mobile communications network 15 12 and base station 13.
Fig. 8 shows by the call control server among Fig. 7 and connects at the incoming call of UE and the flow chart of the control operation carried out.
The incoming call request (step S71) that call control server 1 receives at UE 21.Where the call control server 1 that has received call request appears at (step S72) to subscriber database 4 inquiries as the UE 21 on call intent ground.As Query Result, be arranged in IP network 5 (step S73: be) if identify UE 21, as Fig. 7 step S64 explained, the UE 21 transmission incoming call requests (step S74) of call control server 1 in IP network 5.On the other hand, be arranged in mobile communications network 15 (step S73: not), explained that as the step S65 to S68 of Fig. 7 call control server 1 is to the incoming call request (step S75) of mobile switch system 11 transmission at UE 21 if identify UE 21.
Fig. 9 shows the block diagram according to the another kind of structure of the mobile communication system of the embodiment of the invention.
The basic function of equipment shown in Figure 9 is identical with equipment shown in Figure 1.Yet be with the difference of the structure shown in Fig. 1: mobile switch system 11 directly links to each other with PSTN 31, and media gateway 2 does not link to each other with mobile switch system.
For this reason, even use the network configuration that IP network 5 and mobile communications network 15 directly can not be connected with each other, can two networks be linked to each other via PSTN 31.
In described structure, subscriber database 4 links to each other with mobile switch system 11 with call control server 1 equally.Therefore, location registers operation and such as basic controlling such as the calling route operation in IP network 5 and mobile communications network 15 each also with structure at Fig. 1 in explain those are different.
Next, will with reference to figures 10 to Figure 13 how to explain respectively in Fig. 4 to Fig. 8 at the exhalation connection of UE with realize a formula system during incoming call is connected, described UE has the dual telephone numbers that distributes at IP network and circuit-switched network.In formula system, the call control server of the calling by having accepted to be addressed to UE at the telephone number of IP network is transmitting to the UE that is arranged in circuit-switched network when calling out, carry out control, will convert telephone number at the telephone number of IP network at circuit-switched network, and use telephone number, the calling terminal that is sent to circuit-switched network is connected to described UE at circuit-switched network.
Figure 10 shows when the UE telephone calling, the flow chart of the control operation of being carried out by the UE of Fig. 4.
Call request comprises by the caller number of UE 21 appointments and call intent ground telephone number, and call request is transferred to call control server 1 in the IP network 5 or the mobile switch system 11 in the mobile communications network 15, is used to the connection processing of breathing out.
Figure 11 shows when UE 21 telephone calling, the flow chart of the control operation of being carried out by the call control server among Fig. 4.
